Witteric (in Spanish Witerico, in Portuguese and Galician Viterico) was Visigothic King of Hispania, Septimania and Galicia from 603 to 610.

In April 610, a faction of Catholic nobles assassinated him during a banquet, and had his body dragged ignominiously through the streets (Witteric was buried without honor). The nobles then proclaimed Gundemar, duke of Narbonne, king.
